I was pleasantly surprised by the gameplay, although I did come across a few minor bugs during my playthrough. For example, I noticed that picking up guns through walls was possible, and that there was an issue with gun reloading when swapping weapons. However, these issues have already been identified and listed in other comments, so I'm confident that they will be addressed in future updates.
Despite these minor hiccups, the overall gameplay felt smooth and enjoyable, especially for a single player game. However, considering that this is a multiplayer game, I can see how some of the gameplay mechanics might become frustrating. For instance, the lack of damage fall off means that shotguns can deal devastating damage from a considerable distance, and the pistol seems to outperform assault rifles in terms of damage and fire rate. It would be great to see some balancing adjustments, particularly with the pistol, to ensure a more diverse range of viable options in different combat scenarios.
Another aspect that could use some improvement is the clarity of the jar grenade's damage zone. It was difficult to gauge its actual range based on the limited splash effect it showed, as it seemed to have a much greater impact than it initially appeared. Additionally, I did notice that the shooting mechanics felt a bit stiff, but I understand that you have plans to add leaning and other features to address this.
One small concern I have is that the game seems to be pulling in both fast-paced and tactical elements, which could potentially lead to conflicting gameplay styles. It might be worth considering whether the game should lean more towards one direction or the other to ensure a cohesive experience.
Despite these areas for improvement, I believe that the game has a strong foundation to build upon. You should be proud of what you have created so far, and I am excited to see how the game evolves in the future. Keep up the great work!
